To all whom it may concern:

Be it known that I, ORLANDO E. KELLUM, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Continuous Phonographs, Kinetographs, or the like, of which the following is a specification.

This invention relates to the original making and reproduction ofrecords, such as phonograph and kinetograph records, or anysound or visual or other like records; and

the main object of this invention is the provision of means to make and reproduce a continuous recordof indefinite length.

As is well known, the continuous performance of a kinetograph, phonograph or similar recording or reproducing machine, is limited by certain physical conditions inherent in the records themselves. Thus, the length of continuous performance of a phonograph is limited by the length of the phonograph record; and a kinetograph performance is necessarily limited by the length of one continuous film. My invention provides means for an indefinitely continuous performance by providing @means for unbroken continuance from one record to a subsequent one, the end of the preceding record and the beginning of the succeeding one bc ing so matched and so synchronized that the final eifect is just as if there were only one continuous record of indefinite length.

As hereinbefore stated, my invention may be applied to any machine or device for making or for reproducing records. I herein explain my device in connection with a phonograph and with a kinetograph. but I do not limit my invention to these particular machines. I most particularly explain my invention in connection with a phonograph; this application of my invention typifying its application to other record taking and record reproducing machines.

As appliedto a phonograph, my invention embodies the following described typical elements; I provide two distinct recor devices adapted to drive separate records;

and I provide a constantly running motor (of any desired character), for normally driving either one or the other of the record drivers. There is a special device for initially starting either one or the'other of the record drivers and for starting the corresponding record; and this starting device (preferably in the form of a motor adapted driving to be synchronously energized or controlled) is controlled so that it will bring the next record up to even speedwith the record be- .ing driven by the constantly running motor The connection between the preceding record and the constantly running motor is then broken, and the succeeding record is thendriven to its end. In the meantime the attendant takes the first record off the record driver and substitutes for it another record which will succeed the second record. The third record is brought into play in the same manner that the second one was brought into play. This procedure may go on indefinitely.

\Vhen the records are originally made, they are made on a machine which is, in all essentials a duplicate of the machine on which the records are finally reproduced. The starting of the new records, in either case, is controlled by the same control mechanism.

Thus, whether the records are being made.

or reproduced, the preceding record will be given just so many revolutions before the succeeding record is started up and is thrown into driving relation with the constantly runnin 'motor; and the arrangements are such, t mt once the records have been taken under the control of my device, they will always in future match and synchronize with each other underthe control of my device. In fact, the only essential difference between a record makin machine and a record reproducing machine, according to my invention, is the substitution of means for acting upon the record instead of means adapted" to be operated by the record. When I speak of record, I speak broadly and without limitation. I do not herein limit myself to a phonographic or sound record; but by the.

term record I mean to designate any form of visual, auditory or other record which is made atone time of events or conditions and is reproduced at another time.

I have illustrated preferred embodiments of my invention in the accompanying drawing s, in which, V

igure 1 is a diagram showin my invention as applied to a 'phonog'ap ment is such that, when the table 10 is in this position, the starting motor S is in such position, that, say the left hand solenoid is ready for action, its core 16 being in position to be drawn up. That is, the

starting motor S is ready for action When the solenoids are successively energized beginning with the left hand solenoid 15. As the film 43 moves toward the left the fore- I most aperture 52 comes beneath that brush 'but the last few series, say the last two series of apertures 52, have passed beneath the brushes 47. It will be noted that these series of apertures are cut in the film so that the apertures follow each other at progressivelydecreasing intervals; and this means thatelectrical impulses are sent to the solenoids 15 at progressively decreasing intervals and that the starting motor S is therefore gradually brought up to normal speed.

By the time all but, say, the last three series of apertures have passed the brushes 47, the

starting motor S has been brought up to normal speed and the left hand record 11 is being driven at a speed equal to that of the right hand record 11 driven directly from the constantly running motor M. The last two series of apertures 52 are placed so that the starting motor S will be operated for a short time at its normal uniform speed after that uniform speed has once been attained. As soon as the starting motor has attained the normal speed (as soon as all but the last series of apertures 52* have passed under the brushes 47) an aperture passes beneath the brush 51 and allows the brush 51 to engage the contact plate 46, sending a current through the wire 61 to the electro-magnets 31 of the left hand clutch mechanism C, causing the clutch mechanism to immediately throw to position to connect the shaft 12 with the constantly running motor M. This action taken place at such a time that the pole pieces 31" are exactly opposite the cups 2 6 on the clutch disk 26.

The clutch disk and the cups are constantly revolving in the direction indicated; and the commutator mechanism, including the. film 43 with its perforations, etc, is so cooperated with the motor M, and therefore with the disk 26, that the shaft 12 and the pole pieces 31" W111i].

be revolving in the same direction at the same speed as the clutch disk 26 and the cups 26 and the pole pieces will be exactly opposite the cups when the perforation 60 comes under the brush 51 and the electromagnets 31 act to throw the clutch mechanism to connect the left hand record with the constantly running motor M. When this has been done, theleft hand record is driven by the constantly running motor, as is also the right hand record; and the starting motor S is also being driven at a speed which drives the clutch disks 22 at even speed with the shafts 12. lVhile the starting motor is still in operation, another perforation 62 in the film 43 passes under the brush 48 and current is sent through wire 63 to the mag nets 30 of the right hand clutchmechanism, causing that clutch to throw to position to disconnect the shaft 12 from the motor M and to connect it to the starting motor S. The same control arrangement which provides that the clutch mechanism shall match accurately when throwing in the side connecting to the motor M provides for accurate matching when the clutch mechanism throws in the side connecting with the starting motor S. That is, the starting motor S being in action, the cups 22 of the right hand clutch are exactly opposite the .pole pieces 30 when the magnets 30 are energizedand when the clutch shifts position. Immediately after this, action has taken place, the starting motdcomes to a stop, the shaft 12, at the right? hand, also coming to a stop. The clutches are then in positions opposite to that illustrated in Fig. 1. The attendant then removes the right hand record 11 and replaces it with a record which is to succeed the left hand record 11, registering the pin 10 with the pointer 1O as before. This act of registration also moves the starting motor to its proper position for making its next. start under control of the commutator mechanism. The record 11 at the left hand then rotates until it has been entirely used, when the other sets of perforations 52, 52, etc., come under the brushes 47. The starting motor is again operated to start the right hand record 11; and as soon as the startin motor attains its normal speed, the per oration 64 passes under the brush 49 and a current is sent through wire 65 to the magnet 31 of the right hand clutch C, causing that clutch to return to the position shown inFig. 1 and causing the right hand record to be directly connected to the motor M; During the brief succeeding interval, the two records are driven together in unison by the motor M. This is for the purpose of allowing the record which is be- -ing started to steady down to uniform and vibrationless motion before it is actuallythrown into use. At the end of this short interval another perforation 66 passes beenabled to take continuousrecords at any place and to send those records to-otherfrom the shafts 12 and may include any suitable means for driving a motion picture.

film 100. In the drawings, I have shown a simple arrangement; any of the arrangements now in vogue for intermittently moving the film may be used. I have shown a 1 shutter 101 adapted to cut oil the "light rays.

to or from the objective lenses 102, these shutters being operated by magnets 103 and 104. Energization of either of the magnets 104 will cause the corresponding shutter to assume the position before the objective 102; while energization of either of the magnets 103 will cause the shutter to be reti acted from this position.' The wire 90, hereinbefore described, connects to the magnet 103 of the left hand mechanism in Fig.

5, while the wire 91 connects to the .magnet 104 of the same mechanism, while the magnet 103 of the left hand mechanism is connected by wire 105 with magnet 104 of the right hand mechanism, and magnet 1040f the left hand mechanism is connected by wire 106 with magnet 103 of the right hand mechanism. The other sides of both magnets 103 and 104 of the righthand mechanism are connected to the common wire 89. Current sent through the wire 90 (which occurs-When the right hand film 100 is being finished and when the left hand film is brought into play) will energize the left hand magnet 103 and right hand magnet 104 (in Fig. 5) which will throw the shutters to the position shown in Fig. 6. Current sent through the wire 91 will cause movement of the shutters oppositely. To all intents and purposes, this shutter mechanism operates similarly to the valve mechanism shown in Fig. 4:, the effect of this shutter mechanism being to throw the shutter over the lens of the film just being finished and to' open the shutter over the lens of the film just being started.

When my device is put in action in connection with a kinetograph, the film 100 is placed with a certain mark 110 opposite a,

suitable mark 111 on the apparatus which drives the film and both marks are placed oppositea pointer 112 mounted on some stationarypart of the apparatus. The control mechanism causes} the first film to be fed through a machine; and after a certain definite length of film has been passed through 'the'machine the control mechanism will then start the operation of the starting motor to start the next film. Thus. as shown in Fig. 6, the left hand film is nearing its end and the right hand film is just ready to start (in Fig. 5 it isthe right and left films that are finishing and starting, respectively). The starting" motor will start the right hand film and the corresponding driver mechanism will be thrown into driving relation with the constantly running motor M and the connection of the motor M to the left hand film will then be broken. Just as this action takes place, the last picture on the left hand film (in Fig. 6) will be passing the lens and the first picture on the right hand fil'ln will be just ready to pass. The first picture on the right hand film will be a continuation of the last pic-,

ture on the left hand, just as closely as two pictures on the same film are continuations of each other. When the left hand film is finished, the attendant places the third film, as hereinbefore described, and it is thrown into action as, s'oon as the second film has been finished.

It will be seen that the gist of my invention. is contained in the provision of a pair of record drivers, and a constantlyrunning motor, and means for connecting the motor I.with either of the drivers, and a means operated synchronously with, or in control by, the record being driven by the motor or the motor itself, for throwing a new record into action.
